The geographical distributions of Cd and several other heavy metals (HMs) (Hg, Cu, Ni, Pb, Zn, Cr, As, Co, V) were characterized in 90 (p > 0.05) terra rossa samples across the Anhui karst area. Significant enrichment HM was observed this soil, mainly associated with weathering Cd-enriched carbonate rocks. Then, developed 31 profiles. Our investigations revealed pedogenic processes as domina...

We present results from detailed computations focused on chemical mixing in convective regions of very low mass stars (VLMs) and brown dwarfs (BDs) during deuterium burning. Computations are made both in the instantaneous and in the coupled–diffusive mixing schemes to check which mixing is required to treat these phases. The convective timescale is much shorter than the nuclear time scales for ...

In this work we propose a lightweight scheme for negotiating client’s capabilities in the context of end-end content adaptation for wireless web access. Our method is much less complex then W3C’s proposed CC/PP framework. We suggest that for the purposes of content negotiation all (mobile) clients could be grouped into a few relatively large categories. With this assumption we simplify the CC/P...

Nitrous oxide (N2O) is one of the most important greenhouse gases and a major sink for stratospheric ozone. Estuaries are sites of intense biological production and N2O emissions. We aimed to identify hot spots of N2O production and potential pathways contributing to N2O concentrations in the surface water of the tidal Elbe estuary. During two research cruises in April and June 2015, surface wa...

Strong impacts of drifts on the divertor plasma in–out asymmetry and detachment are demonstrated in DIII-D with an open configuration. For forward toroidal field, BT, i.e., ion B × ?B drift toward divertor, particle flux to inner as represented by Langmuir probe measured saturation current (Jsat), exhibits a double peak structure, electron temperature, lower at target. Reversing BT direction re...

This article reports fibre-optic oxygen measurements on a reactive mine waste heap located in the polymetallic sulphide mine district of Freiberg in south-eastern Germany. The heaped material consists of sulphide-bearing tailings from a processing plant of a lead-zinc mine. Mine waste material was deposited in the water phase after separation of mining ores in a flotation process. The tailing i...

Soil cation exchange property (SCEP) is important in soil development and environmental buffering. However, the variations SCEP its correlation with soil-forming factors subsurface are not fully understood. In this study, we quantified surface as a function of parent material, vegetation, hillslope position, type. Fifty upland profiles from mid-subtropical China were selected. The capacity (CEC...
